The concept is now the basis for a new pain therapy.

Chronic pain once put Marjorie out of commission. Now she's back on her feet thanks to a new therapy, she says, you have to see to believe.

The primal reflex release technique, or PRRT (pert), is the brainchild of physical therapist John Iams.

He says our primitive reflexes can sometimes get stuck in overdrive after they react to an injury, causing pain to persist. But a combination of tapping - karate chopping - and flicking techniques in just the right spot can break the cycle. It's like the reflex hammer doctors use to test the health of your nervous system, taken a step further.

PRRT (pert) makes good money sense because it's cost effective. You'll know if it's going to work in the very first session.

For Marjorie, PRRT (pert) spelled relief, finally getting chronic pain off her back.

The therapy can be used to both assess and treat problems.

Iams is currently teaching the technique to practitioners around the world.
